Acid Rain
Episodic, on the other hand, is rapid change sudden jump in the acidity of water.
Acid deposition may influence forest vegetation and soils. It removes soil nutrients such as calcium and magnesium from soils in high elevation
forests. Acid rain may also help weaken natural defenses of some trees, making them more vulnerable to some diseases and pests. Acid rain
wears away the waxy protective coating of leaves, damaging them and preventing them from being able to photosynthesize properly.
Many animals and insects are sensitive to acidification. Frogs are relatively tolerant of low pH, but the insects upon which they feed are not.
Lichens, mosses and fungi are also particularly sensitive to acid deposition.
Acid rain may lead to increases in nitrogen in forests. Nitrogen is important plant nutrient, but it some situations it leads to nitrogen saturation.
Nitrates can remove additional calcium and magnesium from the soils.
